Unorthodox capitalization
>cathtrender
Catholic + trender; either ironically or seriously describing themself as being not super religious as a joke
>honnish
Had to look this one up, apparently it's a slur used for transexuals who try to transition late and thus don't pass. He is drawing a comparison between his newfound late commitment to Catholicism, and a transexual who transitions late. This reinforces the jokey 'I'm not a transexual' persona he has built up
>atheistmode
atheist + mode; 'mode' is used as a suffix in online circles to describe a state of being.
